Owen Lin 7affe3e3e4 refactor(protocol): isolate legacy item fanout (#30956) ...

## Stack

1. [#30956](https://github.com/openai/codex/pull/30956) — isolate legacy
item fanout ← **this PR**
2. [#30283](https://github.com/openai/codex/pull/30283) — emit canonical
`TurnItem` lifecycle
3. [#30188](https://github.com/openai/codex/pull/30188) — persist
canonical items for paginated threads

## Description

Move legacy `EventMsg` projection code out of the canonical item and
protocol schema modules into `protocol/src/legacy_events.rs`.

This is a behavior-neutral extraction. It keeps the existing
`HasLegacyEvent` API and the existing legacy projections unchanged,
while giving compatibility fanout a single home.

## Why

Canonical `TurnItem` types and wire event schemas should not own the
implementation details for legacy compatibility projections. Isolating
that code makes the boundary explicit and keeps follow-up canonical
lifecycle work easier to review.
